AMSTERDAM – Solid State Logic, the world’s leading provider of tools for creative audio professionals, is demonstrating how IP Audio Networking can deliver significant feature benefits and cost optimisation in audio routing systems for broadcast production at IBC 2014 (Hall 8, D83). The insightful demonstration serves as a showcase for SSL’s growing ‘Network I/O’ broadcast audio interface range and shows how the new product line and SSL digital broadcast consoles can be elegantly interfaced with devices from more than 100 different manufacturers using a Dante IP Audio Network. The new SSL Network I/O range consists of ‘MADI-Bridge,’ providing 64 bidirectional channels of fully redundant MADI-to-network bridging with front panel confidence headphone monitoring; ‘SDI,’ bridging eight 3G-SDI embedders and eight de-embedders to the network, or MADI with internal per channel routing; and ‘Stagebox,’ which provides eight channels of mic/line I/O (using SSL’s renowned SuperAnalogue™ mic pres) with redundant network connectivity. The demonstration includes four SSL consoles (2 x C10, C100 and Live) networked with third-party devices from Shure and Sound Devices and also features SSL’s ‘LMS-16’ Loudness Monitoring system connected directly to the network. With Dante committed to conform with AVB standards and AES67, the SSL Network I/O range is ready for future networked audio developments.

The case for IP Audio Networking and Dante for broadcast:

Audinate’s Dante technology is very well established in professional audio for live production and installation sectors, with many significant broadcast manufacturers recently adopting the technology. In total, more than 150 manufactures have licensed Dante, giving system designers over 350 products to use together. The demonstration at IBC sets out a very strong case for why Dante is the right choice for forward-thinking audio routing for broadcast production applications.

Dante uses IP networking. The backbone of IT infrastructures worldwide, IP networking is a lower cost technology that benefits from developments and cost competition in much larger industries than broadcasting. Cat 5, Cat 6, fibre cabling and off-the-shelf network switch hardware come at a fraction of the cost of comparable TDM-based solutions and are guaranteed to be supported by international standards and major manufacturers. IP networks are scalable and can grow easily as budgets and needs require. In addition to transporting audio, they can also support other data traffic pertinent to the workflow. The function of routing, so expensive and complex to implement in TDM systems, can be accomplished using standard network switch hardware and conventionally managed router software. Ethernet/IP connectivity simplifies the interfacing to a range of other systems such as Intercoms and Station Automation. Network switches with industry-standard redundancy protocols are readily available and enable IP-based networks to meet the highest levels of redundancy demanded by Broadcasters.

SSL chose to utilise Audinate’s Dante Technology because it meets their technical requirements and has the critical mass that other solutions can’t match. Developed using existing standards, including IEEE and IETF, Dante is deployable on any standard IP infrastructure and can share networks with other types of traffic. A key factor in SSL’s decision was Audinate’s commitment to converge with the AVB standards and to conform with AES67. These clear migration paths mean investment today is future-proof and a single device will be able to function in any of these environments. Audinate’s clearly defined device discovery mechanism also means any device is plug-and-play, and network standards allow you to tailor your infrastructure to define if you want this to be the case.

· Absolute Resilience: catastrophic failure of a single device will have no effect on any other devices in the network.

· Standards compliant: IEEE and IETF compliant, thus deployable on and can mix with traffic on any standard IP infrastructure. Committed to converge with AVB standards and conform with AES67.

About SSL’s ‘Network I/O’ Range:

Network I/O: MADI-Bridge:

MADI-Bridge provides an interface between a Dante IP Audio Network and MADI. With 64 channels per Bridge at 48kHz, or 32 channels at 96kHz, redundant MADI, IP Network ports and PSU, the Bridge is built for uninterrupted fully-redundant operation. In addition to the built-in clock redundancy in Dante controller, the MADI-Bridge includes a pair of sync inputs for use as a self-redundant Dante Grand Master PTP clock. MADI-Bridge also features a front panel headphone socket, with rotary level control, and built-in headphone monitor routing to truly replace traditional patch bay routing and fault-finding functionality with equivalents in the IP Audio domain. GPIO connections allow for transfer of tally info and switching functions across the network with the Audio. MADI-Bridge is being shown for the first time at IBC 2014 featuring 96kHz to 48kHz Sample Rate Conversion functionality and an innovative new ‘Split Mode’ feature. This allows the pair of MADI connectors to be used independently (rather than in their usual redundant mode) for bi-directional split/combine operation. This means that, for example, two 32 channel 96kHz MADI feeds can be combined to from one 64 channel 48kHz Dante stream.

Network I/O: Stagebox:

A Mic/Line Network I/O device for use on any Broadcast Studio floor, Stagebox brings SSL’s renowned SuperAnalogue™ preamp design to the interoperable IP Audio Network market. With eight Mic/Line inputs, eight Line outputs and a pair of redundant network connections, Stagebox allows easy deployment of mic pres and speaker feeds where needed in a studio. The Network I/O’s plug-and-play feature allows devices to easily be moved, even between studios, and retain routing and settings, if required. Clear signal present, phantom power and local attention LEDs provide intuitive front panel feedback.
